By Mike Simpson

When candidates prepare for interviews, they usually focus on highlighting their leadership, communication, teamwork, and similar crucial soft skills . However, not everyone gets ready for problem-solving interview questions. And that can be a big mistake.

Problem-solving is relevant to nearly any job on the planet. Yes, it’s more prevalent in certain industries, but it’s helpful almost everywhere.

Regardless of the role you want to land, you may be asked to provide problem-solving examples or describe how you would deal with specific situations. That’s why being ready to showcase your problem-solving skills is so vital.

If you aren’t sure who to tackle problem-solving questions, don’t worry, we have your back. Come with us as we explore this exciting part of the interview process, as well as some problem-solving interview questions and example answers.

What Is Problem-Solving?

When you’re trying to land a position, there’s a good chance you’ll face some problem-solving interview questions. But what exactly is problem-solving? And why is it so important to hiring managers?

Well, the good folks at Merriam-Webster define problem-solving as “the process or act of finding a solution to a problem.” While that may seem like common sense, there’s a critical part to that definition that should catch your eye.

What part is that? The word “process.”

In the end, problem-solving is an activity. It’s your ability to take appropriate steps to find answers, determine how to proceed, or otherwise overcome the challenge.

Being great at it usually means having a range of helpful problem-solving skills and traits. Research, diligence, patience, attention-to-detail , collaboration… they can all play a role. So can analytical thinking , creativity, and open-mindedness.

But why do hiring managers worry about your problem-solving skills? Well, mainly, because every job comes with its fair share of problems.

While problem-solving is relevant to scientific, technical, legal, medical, and a whole slew of other careers. It helps you overcome challenges and deal with the unexpected. It plays a role in troubleshooting and innovation. That’s why it matters to hiring managers.

How to Answer Problem-Solving Interview Questions

Okay, before we get to our examples, let’s take a quick second to talk about strategy. Knowing how to answer problem-solving interview questions is crucial. Why? Because the hiring manager might ask you something that you don’t anticipate.

Problem-solving interview questions are all about seeing how you think. As a result, they can be a bit… unconventional.

These aren’t your run-of-the-mill job interview questions . Instead, they are tricky behavioral interview questions . After all, the goal is to find out how you approach problem-solving, so most are going to feature scenarios, brainteasers, or something similar.

So, having a great strategy means knowing how to deal with behavioral questions. Luckily, there are a couple of tools that can help.

First, when it comes to the classic approach to behavioral interview questions, look no further than the STAR Method . With the STAR method, you learn how to turn your answers into captivating stories. This makes your responses tons more engaging, ensuring you keep the hiring manager’s attention from beginning to end.

Now, should you stop with the STAR Method? Of course not. If you want to take your answers to the next level, spend some time with the Tailoring Method , too.

With the Tailoring Method, it’s all about relevance. So, if you get a chance to choose an example that demonstrates your problem-solving skills, this is really the way to go.

Top 3 Problem-Solving-Based Interview Questions

Alright, here is what you’ve been waiting for: the problem-solving questions and sample answers.

While many questions in this category are job-specific, these tend to apply to nearly any job. That means there’s a good chance you’ll come across them at some point in your career, making them a great starting point when you’re practicing for an interview.

So, let’s dive in, shall we? Here’s a look at the top three problem-solving interview questions and example responses.

1. Can you tell me about a time when you had to solve a challenging problem?

In the land of problem-solving questions, this one might be your best-case scenario. It lets you choose your own problem-solving examples to highlight, putting you in complete control.

When you choose an example, go with one that is relevant to what you’ll face in the role. The closer the match, the better the answer is in the eyes of the hiring manager.

EXAMPLE ANSWER:

“While working as a mobile telecom support specialist for a large organization, we had to transition our MDM service from one vendor to another within 45 days. This personally physically handling 500 devices within the agency. Devices had to be gathered from the headquarters and satellite offices, which were located all across the state, something that was challenging even without the tight deadline. I approached the situation by identifying the location assignment of all personnel within the organization, enabling me to estimate transit times for receiving the devices. Next, I timed out how many devices I could personally update in a day. Together, this allowed me to create a general timeline. After that, I coordinated with each location, both expressing the urgency of adhering to deadlines and scheduling bulk shipping options. While there were occasional bouts of resistance, I worked with location leaders to calm concerns and facilitate action. While performing all of the updates was daunting, my approach to organizing the event made it a success. Ultimately, the entire transition was finished five days before the deadline, exceeding the expectations of many.”

2. Describe a time where you made a mistake. What did you do to fix it?

While this might not look like it’s based on problem-solving on the surface, it actually is. When you make a mistake, it creates a challenge, one you have to work your way through. At a minimum, it’s an opportunity to highlight problem-solving skills, even if you don’t address the topic directly.

When you choose an example, you want to go with a situation where the end was positive. However, the issue still has to be significant, causing something negative to happen in the moment that you, ideally, overcame.

“When I first began in a supervisory role, I had trouble setting down my individual contributor hat. I tried to keep up with my past duties while also taking on the responsibilities of my new role. As a result, I began rushing and introduced an error into the code of the software my team was updating. The error led to a memory leak. We became aware of the issue when the performance was hindered, though we didn’t immediately know the cause. I dove back into the code, reviewing recent changes, and, ultimately, determined the issue was a mistake on my end. When I made that discovery, I took several steps. First, I let my team know that the error was mine and let them know its nature. Second, I worked with my team to correct the issue, resolving the memory leak. Finally, I took this as a lesson about delegation. I began assigning work to my team more effectively, a move that allowed me to excel as a manager and help them thrive as contributors. It was a crucial learning moment, one that I have valued every day since.”

3. If you identify a potential risk in a project, what steps do you take to prevent it?

Yes, this is also a problem-solving question. The difference is, with this one, it’s not about fixing an issue; it’s about stopping it from happening. Still, you use problem-solving skills along the way, so it falls in this question category.

If you can, use an example of a moment when you mitigated risk in the past. If you haven’t had that opportunity, approach it theoretically, discussing the steps you would take to prevent an issue from developing.

“If I identify a potential risk in a project, my first step is to assess the various factors that could lead to a poor outcome. Prevention requires analysis. Ensuring I fully understand what can trigger the undesired event creates the right foundation, allowing me to figure out how to reduce the likelihood of those events occurring. Once I have the right level of understanding, I come up with a mitigation plan. Exactly what this includes varies depending on the nature of the issue, though it usually involves various steps and checks designed to monitor the project as it progresses to spot paths that may make the problem more likely to happen. I find this approach effective as it combines knowledge and ongoing vigilance. That way, if the project begins to head into risky territory, I can correct its trajectory.”

17 More Problem-Solving-Based Interview Questions

In the world of problem-solving questions, some apply to a wide range of jobs, while others are more niche. For example, customer service reps and IT helpdesk professionals both encounter challenges, but not usually the same kind.

As a result, some of the questions in this list may be more relevant to certain careers than others. However, they all give you insights into what this kind of question looks like, making them worth reviewing.

Here are 17 more problem-solving interview questions you might face off against during your job search:

• How would you describe your problem-solving skills?
• Can you tell me about a time when you had to use creativity to deal with an obstacle?
• Describe a time when you discovered an unmet customer need while assisting a customer and found a way to meet it.
• If you were faced with an upset customer, how would you diffuse the situation?
• Tell me about a time when you had to troubleshoot a complex issue.
• Imagine you were overseeing a project and needed a particular item. You have two choices of vendors: one that can deliver on time but would be over budget, and one that’s under budget but would deliver one week later than you need it. How do you figure out which approach to use?
• Your manager wants to upgrade a tool you regularly use for your job and wants your recommendation. How do you formulate one?
• A supplier has said that an item you need for a project isn’t going to be delivered as scheduled, something that would cause your project to fall behind schedule. What do you do to try and keep the timeline on target?
• Can you share an example of a moment where you encountered a unique problem you and your colleagues had never seen before? How did you figure out what to do?
• Imagine you were scheduled to give a presentation with a colleague, and your colleague called in sick right before it was set to begin. What would you do?
• If you are given two urgent tasks from different members of the leadership team, both with the same tight deadline, how do you choose which to tackle first?
• Tell me about a time you and a colleague didn’t see eye-to-eye. How did you decide what to do?
• Describe your troubleshooting process.
• Tell me about a time where there was a problem that you weren’t able to solve. What happened?
• In your opening, what skills or traits make a person an exceptional problem-solver?
• When you face a problem that requires action, do you usually jump in or take a moment to carefully assess the situation?
• When you encounter a new problem you’ve never seen before, what is the first step that you take?

Putting It All Together

At this point, you should have a solid idea of how to approach problem-solving interview questions. Use the tips above to your advantage. That way, you can thrive during your next interview.

8 Tough Brain Teaser Interview Questions and Answers in 2024

Brain teaser interview questions, also known as puzzle or logic questions, are designed to challenge candidates and evaluate their problem-solving, critical thinking, and creativity skills. They are usually asked in job interviews for positions that require analytical thinking or problem-solving abilities. Companies use these questions to assess a candidate’s ability to respond to unexpected and challenging situations, which can indicate their potential to excel in the role.

The importance of brain teaser questions lies in their ability to go beyond a candidate’s resume or credentials. Unlike traditional interview questions, which may have a predetermined answer or are related to a candidate’s job experience, brain teasers can reveal how a candidate thinks and approaches complex problems. They can also demonstrate a candidate’s ability to think quickly, be creative, and demonstrate their character and personality under pressure.

Common Types of Brain Teaser Interview Questions

Brain teasers can take many different forms, but they all have one common feature: they are designed to challenge you to think creatively and logically. Some of the common types of brain teaser interview questions include:

• Logic puzzles: These questions involve various scenarios or situations designed to test your logical reasoning skills.
• Numerical puzzles: These questions involve mathematical problems or puzzles that require you to use your math skills to solve.
• Lateral thinking puzzles: These are puzzles that can be solved through creative or unorthodox thinking.
• Competency-based questions: These questions are often hypothetical and ask you to demonstrate how you would respond in a specific situation.

The Purpose of Brain Teaser Interview Questions

The purpose of brain teaser questions is to assess how a candidate thinks and approaches complex problems. They are often used by companies to evaluate a candidate’s potential rather than their specific skills or experience. Brain teaser questions may also be used to evaluate a candidate’s ability to work under pressure, think creatively, be adaptable, and tackle complex problems. By asking these questions, employers can gain insights into how candidates solve problems and make decisions, which can be valuable in assessing their potential for the job.

Brain teaser interview questions are designed to challenge candidates and evaluate their problem-solving, critical thinking, and creativity skills. They are an important tool for hiring managers to assess the potential of candidates and provide insights into how they approach complex problems. It is essential for candidates to prepare for these questions to demonstrate their potential to excel in the role.

How to Prepare for Brain Teaser Interview Questions

When preparing for a brain teaser interview, it’s important to keep in mind that these types of questions are designed to test your problem-solving and critical thinking skills. With a few tips and best practices, you can feel more confident and prepared to tackle these challenging interview questions.

A. Tips for Answering Brain Teaser Interview Questions

Take your time: Brain teaser questions are meant to be challenging and require careful thought. Take a moment to gather your thoughts and ask clarifying questions before jumping into an answer.

Break down the problem: Often, brain teasers are presented as complex problems that can seem overwhelming. Break the problem down into smaller parts to identify patterns and possible solutions.

Use logic and reasoning: Brain teasers often involve patterns, sequences, or logic puzzles. Use your analytical skills to identify commonalities and solve the problem logically.

Show your work: As you work through a brain teaser, be sure to share your thought process with the interviewer. This can demonstrate your problem-solving skills and give insight into how you approach difficult situations.

B. Best Practices for Preparing for Brain Teaser Interview Questions

Research common brain teasers: There are many brain teasers that are commonly asked during interviews. Familiarize yourself with these questions and practice solving them ahead of time.

Practice under pressure: In addition to researching and solving brain teasers, try practicing with time constraints. This can simulate the pressure of an interview and prepare you for thinking on your feet.

Challenge yourself: As you prepare for brain teaser questions, don’t shy away from difficult problems. Push yourself to solve more complex challenges to build your problem-solving skills.

Get feedback: Practice solving brain teasers with a friend or colleague and ask for feedback on your performance. This can help you identify areas for improvement and refine your approach.

C. The Benefits of Preparing for Brain Teaser Interview Questions

Preparing for brain teaser interview questions can have numerous benefits for your career. Not only does it demonstrate your analytical and problem-solving skills, but it can also improve your overall critical thinking abilities. Additionally, practicing under pressure can help you feel more comfortable in high-stress situations, which can be beneficial in any work environment. By taking the time to prepare for brain teaser questions, you can feel more confident and prepared to tackle any challenge that comes your way during an interview.

The 8 Tough Brain Teaser Interview Questions and Answers

As a job seeker, it’s important to be prepared for any questions that may come your way during an interview, including tough brain teasers. These questions are designed to assess your problem-solving abilities and critical thinking skills. Here are eight examples of tough brain teaser interview questions and answers that you can use to help you prepare for your next job interview:

Question 1: Example Question and Answer

Q: How many golf balls can fit in a school bus?

A: To answer this question, you need to make some assumptions. Let’s assume the school bus is 40 feet long, 8 feet wide, and 6 feet high. That means it has a volume of 1,920 cubic feet. Now, let’s assume a golf ball is 1.68 inches in diameter. That means each golf ball has a volume of about 2.65 cubic inches. To fill the entire school bus with golf balls, we need to convert the volume of the school bus to cubic inches and then divide by the volume of a single golf ball.

• Convert school bus volume to cubic inches:

40 ft x 12 in/ft = 480 in (length) 8 ft x 12 in/ft = 96 in (width) 6 ft x 12 in/ft = 72 in (height) 480 in x 96 in x 72 in = 331,776 cubic inches

• Divide school bus volume by golf ball volume:

331,776 cubic inches ÷ 2.65 cubic inches per golf ball = 125,233 golf balls

So, the answer is approximately 125,233 golf balls can fit in a school bus.

Question 2: Example Question and Answer

Q: How would you design a spice rack for blind people?

A: This question is designed to assess your creativity and problem-solving abilities. A possible answer might include:

• Use different textures or shapes on each spice bottle to allow for easy differentiation by touch.
• Label the spices using braille or embossed letters.
• Make the spice rack adjustable or modular to accommodate different types and sizes of spice bottles.
• Include a simple guide or key to help users easily locate the desired spice.

Question 3: Example Question and Answer

Q: You are standing in front of three light switches. One of them controls a light bulb inside a closed room. You cannot see into the room. You can only open the door once, and after that, you cannot touch the switches. How do you figure out which switch controls the light bulb?

A: To solve this brain teaser, you need to follow a specific set of steps:

• Turn on one of the switches and leave it on for a few minutes.
• Turn off that switch and turn on another switch.
• If the light bulb is on, then you know that the switch you just turned on controls the light bulb. If the light bulb is off but warm to the touch, then you know that the switch you initially turned on and then turned off controls the light bulb. Finally, if the light bulb is off and cool to the touch, then the remaining switch controls the light bulb.

Question 4: Example Question and Answer

Q: You have a 3-gallon jug and a 5-gallon jug. How can you measure exactly 4 gallons of water using only these two jugs?

A: Here’s a step-by-step solution:

Fill the 5-gallon jug to its maximum capacity. Pour the 5 gallons of water from the 5-gallon jug into the 3-gallon jug, which will leave 2 gallons of water in the 5-gallon jug. Empty the 3-gallon jug. Pour the 2 gallons of water from the 5-gallon jug into the empty 3-gallon jug. Fill the 5-gallon jug to its maximum capacity again. Pour enough water from the 5-gallon jug into the 3-gallon jug until the 3-gallon jug is full. This will leave 4 gallons of water in the 5-gallon jug.

Now you have exactly 4 gallons of water in the 5-gallon jug.

Question 5: Example Question and Answer

Q: How many trailing zeros are there in the number 100 factorial (100!)?

A: To determine the number of trailing zeros in 100!, you need to identify the number of factors of 5 since multiples of 10 (which have one trailing zero) are created by the combination of factors of 2 and 5.

Counting the number of multiples of 5 less than or equal to 100 gives you 20. However, there are multiples of 5 squared (25), multiples of 5 cubed (125), and so on. So, you need to consider the additional multiples of 5^2, 5^3, and so on that divide 100.

Dividing 100 by 5^2 gives you 4, and there are no multiples of 5^3 or higher within the range of 1 to 100. Therefore, the total number of trailing zeros in 100! is 20 + 4 = 24.

Question 6: Example Question and Answer

Q: How many squares are there on a chessboard?

A: To count the number of squares on a chessboard, you need to consider squares of different sizes. Start by counting the 64 individual squares (1×1). Then, count the 49 squares that are formed by combining four individual squares (2×2). Continue this process for squares of size 3×3, 4×4, and so on until you reach the largest square, which is the entire chessboard (8×8).

The total number of squares on a chessboard is the sum of all these counts:

1×1 squares: 64 2×2 squares: 49 3×3 squares: 36 4×4 squares: 25 5×5 squares: 16 6×6 squares: 9 7×7 squares: 4 8×8 squares: 1

Adding these counts together, you get a total of 204 squares on a chessboard.

Behavioral Questions vs. Brain Teaser Questions

A. definition and differences between behavioral and brain teaser questions.

During job interviews, employers often ask job seekers a variety of questions to assess their problem-solving, critical thinking, and communication skills. Two types of questions that you may encounter during a job interview are behavioral and brain teaser questions.

Behavioral Questions:  Behavioral questions inquire about how you have handled previous work situations or challenges. These questions are designed to allow the interviewer to understand your past work experiences, your response to various situations, and your attitude towards work. Behavioral questions require you to provide specific examples of how you have handled specific work scenarios in the past.

Brain Teaser Questions:  Brain teaser questions are designed to assess your thought process, problem-solving capabilities, and creativity. These types of questions do not necessarily have a right or wrong answer. Typically, brain teaser questions are seemingly unrelated to the job or industry and may be puzzles, riddles, or other types of mind-bending challenges that rely on logic and critical thinking to solve.

The fundamental difference between behavioral and brain teaser questions is that behavioral questions look at how you have responded to situations in the past, while brain teaser questions assess your ability to think on your feet and solve unfamiliar problems quickly.

B. How to Prepare for Behavioral and Brain Teaser Questions

The best way to prepare for behavioral and brain teaser questions is to practice. Try to anticipate which types of questions may be asked and prepare specific examples to share during the interview.

For behavioral questions, review the job description and requirements before the interview. Then, think of specific examples that demonstrate how you have handled similar situations in the past. Make sure to use the STAR technique (Situation, Task, Action, Result) when answering behavioral questions to showcase your problem-solving skills effectively.

When it comes to brain teaser questions, the best way to prepare is by working on logic puzzles, brainteasers, and riddles. You can find plenty of resources online or in books to help you practice. Work on puzzles that stretch your mind and challenge you to expand your thinking.

C. Tips for Answering Behavioral and Brain Teaser Questions

Here are some tips to keep in mind when answering behavioral and brain teaser questions:

Behavioral Questions:

Be specific: Use concrete examples to illustrate your answer. Provide clear details of what you did and why you did it.

Focus on your actions: Highlight the actions you took and the decisions you made in response to the situation.

Use the STAR technique: The STAR technique is Situation, Task, Action, and Result. Use this framework to structure your answers and showcase your problem-solving abilities effectively.

Brain Teaser Questions:

Clarify the question: Ask the interviewer to repeat or explain the question if you don’t understand it fully.

Take your time: Don’t rush to answer the question.

The Role of Brain Teaser Questions in the Hiring Process

When it comes to the hiring process, many companies are turning to brain teaser questions as a way to assess a candidate’s critical thinking and problem-solving abilities. Here, we will explore how hiring managers use brain teaser questions, the benefits of using them, and the limitations that should be considered.

A. How Hiring Managers Use Brain Teaser Questions

Hiring managers use brain teaser questions to get a sense of a candidate’s ability to think on their feet, approach problems creatively, and work through challenging situations. These types of questions often require the candidate to use logic, reasoning, and unconventional thinking to come up with a solution.

Some hiring managers use brain teasers as a way to gauge a candidate’s personality and how they handle pressure. These questions can reveal a lot about how a candidate works under stress, their communication skills, and how they adapt to change.

B. The Benefits of Using Brain Teaser Questions

There are several benefits to using brain teaser questions in the hiring process. First and foremost, they allow hiring managers to quickly assess a candidate’s critical thinking skills, which are essential for success in many roles.

Brain teasers also help hiring managers get a sense of a candidate’s personality and how well they may fit into the company culture. By asking questions that require unconventional thinking and problem-solving, hiring managers can get a sense of how a candidate approaches challenges and whether they are a good fit for the team.

C. The Limitations of Brain Teaser Questions

While brain teaser questions can be a useful tool in the hiring process, it is important to recognize their limitations. First and foremost, they should not be the sole criteria on which a candidate is evaluated.

It is also important to recognize that brain teaser questions may not accurately reflect a candidate’s ability to perform the specific job they are applying for. While these questions can be useful in assessing critical thinking and problem-solving skills, they may not be relevant to the day-to-day tasks of the job.

Finally, it is important to ensure that brain teaser questions are fair and not biased against certain candidates. Questions should be designed to challenge all candidates equally, regardless of their background or experience.

Brain teaser questions can be a useful tool in the hiring process, allowing hiring managers to quickly assess a candidate’s critical thinking skills and personality. However, it is important to recognize their limitations and ensure they are used fairly and effectively.

The Impact of Brain Teaser Questions on Job Performance

Incorporating brain teaser questions during the hiring process has become increasingly popular as hiring managers aim to assess a candidate’s ability to think critically under pressure. However, there is a debate on whether brain teasers accurately predict job performance.

A. The Relationship between Brain Teaser Performance and Job Performance

Some studies suggest that there is a positive correlation between brain teaser performance and job performance. Candidates who score well on brain teasers tend to perform better on the job. This is because brain teasers test a candidate’s ability to think logically, creatively and make sound decisions when faced with complex problems.

B. How Hiring Managers Evaluate Brain Teaser Performance

Hiring managers evaluate brain teaser performance in different ways. Some use it as a primary factor in deciding whether to hire a candidate, while others use it as one of many factors to evaluate a candidate. They assess a candidate’s performance by examining how quickly and efficiently they answer the questions, their thought processes, and the accuracy of their answers.

C. The Potential Risks of Overemphasizing Brain Teaser Performance

While brain teasers can be an effective tool for evaluating candidates, they also come with potential risks. Overemphasizing brain teaser performance may lead to the exclusion of highly qualified candidates who may not perform well under pressure. It may also place undue stress on candidates, leading to anxiety and nervousness that can negatively impact their performance.

Furthermore, brain teasers may only assess an individual’s problem-solving ability, whereas other important job-specific skills may not be evaluated. Thus, it is essential to use brain teasers as part of a more comprehensive evaluation process.

While brain teasers can provide valuable insights into a candidate’s critical thinking ability, it should not be the sole criterion for evaluating job performance. It is important to use a combination of various assessment tools to ensure a fair and accurate evaluation of a candidate’s suitability for the role.

The Future of Brain Teaser Questions in the Hiring Process

A. trends in the use of brain teaser questions.

As the job market becomes increasingly competitive, hiring managers are looking for new ways to identify the top candidates for their open positions. One trend that has emerged in recent years is the use of brain teaser questions during the hiring process.

Brain teaser questions are designed to test a candidate’s problem-solving skills, creativity, and ability to think on their feet. They can be used in a variety of industries and job roles, from finance and accounting to marketing and technology.

Some companies use pre-designed brain teaser questions, while others prefer to create their own based on the specific job requirements. As the use of brain teaser questions becomes more widespread, it’s important for hiring managers to ensure that the questions are relevant to the job and provide a true measure of a candidate’s abilities.

B. The Benefits and Risks of Using Brain Teaser Questions

The use of brain teaser questions in the hiring process has both benefits and risks. On the one hand, they can help managers identify candidates who are able to think critically and creatively, which may be particularly important for roles that require problem-solving skills.

Brain teasers can also be a good way to differentiate between candidates who may have similar qualifications and experience. Additionally, they can give candidates a chance to showcase their skills in a way that traditional interview questions may not.

However, there are also risks associated with using brain teaser questions in the hiring process. For one, they may not be a fair indicator of a candidate’s overall abilities or potential for success in a role. Additionally, some candidates may find them intimidating, which could create a negative impression of the company.

To mitigate these risks, it’s important for hiring managers to use brain teaser questions in conjunction with other types of interview questions and assessments. Additionally, they should be transparent about the use of brain teasers and provide candidates with adequate preparation time before the interview.

C. Future Innovations in Brain Teaser Interviews

As technology continues to evolve and change the way we work, it’s likely that we’ll continue to see innovations in the use of brain teasers during the hiring process. One trend that may emerge is the use of virtual reality or augmented reality to provide candidates with more dynamic and engaging brain teaser experiences.

Another potential innovation is the use of machine learning algorithms to analyze a candidate’s responses to brain teaser questions and provide more nuanced insights into their problem-solving abilities.

Ultimately, the future of brain teaser questions in the hiring process will be shaped by a variety of factors, including advances in technology, changes in the job market, and evolving attitudes toward hiring practices. As hiring managers continue to explore the use of brain teasers, it will be important to strike a balance between their potential benefits and risks.

8 Tough Brain Teaser Interview Questions from Google, Apple and Facebook

By Biron Clark

Published: November 16, 2023

Silicon Valley tech companies are famous for asking some pretty crazy brain-teaser interview questions… I wanted to find out exactly what these questions involve. And how difficult they are to answer. So I spent a day on Glassdoor.com and a few other sites to come up with the 8 hardest and most interesting logical interview questions out there. And not just from any companies…We’re going to look at 4 tech giants known for having the toughest interviews:

Time to see how many you can answer!

Facebook Brain Teaser Interview Questions and Answers:

Question 1:.

A Russian gangster kidnaps you. He puts two bullets in consecutive order in an empty six-round revolver, spins it, points it at your head and shoots. *click* You’re still alive. He then asks you, “do you want me to spin it again and fire or pull the trigger again right away?” For each option, what is the probability that you’ll be shot?

Answer…

The key hint here is that the bullets were loaded adjacent to each other.

There are 4 ways to arrange the revolver with consecutive bullets so that the first shot is blank. These are the possible scenarios:

The other two scenarios would have meant you got shot on the first attempt. (BBxxxx) or (BxxxxB)

Now look at the second slot in those 4 possible scenarios above. Your odds of getting shot are 1/4 or 25%. (Only #1 would get you shot)

But if you respin… there are 2 bullets remaining and 6 total slots. 2/6 or 33%.

Question 2:

You’re about to get on a plane to Seattle. You want to know  if it’s raining. You call 3 random friends who live there and ask each if it’s raining. Each friend has a 2/3 chance of telling you the truth and a 1/3 chance of messing with you by lying. All 3 friends tell you that “Yes” it is raining. What is the probability that it’s actually raining in Seattle?  

You only need 1 of your friends to be telling the truth for it to be raining in Seattle.

It’s fastest just to calculate the odds that all 3 are lying, and it’s not raining.

Each friend has a 1/3 chance of lying. Multiply the odds together… you get 1/27 (1/3 * 1/3 * 1/3).

We’re not done yet though… 1/27 is the probability that all 3 friends lied at the same time.

The probability that at least 1 told you the truth? 26/27 or around a 96% that it’s raining in Seattle.

Question 3:.

You have a 3 gallon jug and 5 gallon jug, how do you measure out exactly  4 gallons?  

We know we can’t get the final result in the 3 gallon jug. It’ll overflow. We need to end up with 4 gallons in the 5 gallon jug.

First fill the 3 gallon jug.

Then pour the 3 gallons into the 5 gallon jug.

Now the 3 gallon jug is empty, and the 5 gallon jug has 3 gallons in it.

Fill the 3 gallon jug again. Slowly pour into the 5 gallon jug. Only 2 gallons will fit because it already has 3. Now it’s full.

Exactly 1 gallon is left in the 3 gallon jug.

Dump out the 5 gallon jug.

Pour your 1 gallon into the 5 gallon jug.

Fill up the 3 gallon jug one more time and pour it into the 5 gallon jug! You have exactly 4 gallons (and possibly a job at Google)

Question 4:

Why are manhole covers round?

Good news: If you’re tired of math questions this one will give you a break. Manhole covers are round because it’s the only shape that cannot fall through itself. The cover can never accidentally fall down the hole. Microsoft has been known to ask this question and according to Glassdoor.com, Google is asking this too now.

Apple Brain Teaser Interview Questions and Answers:

Question 5:  .

There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The boxes have been incorrectly labeled such that no label identifies the actual contents of its box. Opening just one box, and without looking in the box, you take out one piece of fruit. By looking at the fruit, how can you immediately label all of the boxes correctly?  

So, you know all 3 boxes are incorrectly labeled.

Go to the box labeled “Apples + Oranges.” Since the label is wrong, it must have one or the other.

This is the box to take one piece of fruit from. Whichever comes out is what that box contains. If you took out an apple, the box has only apples. If you took out an orange, vice versa.

Here’s where it gets tricky a bit tricky. But we’re almost done…

Let’s say you grabbed an apple. Move the “Apples” label over to that box. Now it’s correctly labeled.

You know the “Oranges” box is still labeled wrong (because all 3 were labeled wrong to start and you haven’t touched it). And you know it’s not “Apples”.

So it has to be “Apples + Oranges”.

The last box is “Oranges”.

The same process above would work if you had pulled out an orange at the start.

Question 6: 

You have 100 coins laying flat on a table, each with a head side and a tail side. 10 of them are heads up, 90 are tails up. You can’t feel, see or in any other way find out which 10 are heads up. Your goal: split the coins into two piles so there are the same number of heads-up coins in each pile.  

By pure coincidence… this is a trick my friend Mike showed me last summer. It blew my mind back then but hopefully it’ll make sense as I write it out.

You want an equal number of heads in each pile. There are currently 10 of them. You don’t know which but it doesn’t matter. All you have to do… take any 10 coins out of the 100, put them into a separate pile, and flip those 10 over.

That’s pile #1.

Pile #2 is the remaining 90 coins, unflipped. Just leave them.

You’re done. Seriously.

You can do this with any number of coins. If you had 20 coins, and 18 were heads, you’d need to take 18 of them (it doesn’t matter which) into a separate pile and flip those 18. That’s pile #1.

If you had 10 coins and 3 were heads, you’d take 3 random coins into a new pile and flip those 3 for your first pile, and the rest are your second pile.

Crazy right?

If you don’t believe me just grab some pennies and try it. There are no exceptions and it doesn’t need to be an even amount of “heads” to begin with either. It can also be zero. Or all.

LinkedIn Brain Teaser Interview Questions and Answers:

Question 7: .

You’re in a room with three light switches, each of which c ontrols one of three light bulbs in the next room. You need to determine which switch controls which bulb. All lights are off to begin, and you can’t see into one room from the other. You can inspect the other room only once. How can you find out which switches are connected to which bulbs?  

Let’s call the switches 1, 2, and 3.

Leave switch 1 off.

Turn switch 2 on for ten minutes.

Now turn it off and quickly turn on switch 3.

Go into the room and inspect…

The bulb that is still warm but not lit up is controlled by switch 2. The one that’s currently lit up is switch 3. The last one is switch 1.

Question 8: 

How many golf balls would fit into a Boeing 747?

This last one is tough, but they don’t expect you to get an accurate answer. If you get a question like this (and there are a ton of variations- basketballs in a room, cellphones in Manhattan, etc.) they want to see your thought process. The hiring manager is going to look at how you work your way through it and attempt to figure it out.

If you can break a problem down into smaller pieces, stay calm, and get an answer that’s not perfect but reasonably close, you’ve done great.

They might not even know the answer. They just want to see how you approach something that’s very difficult.

On a Practical Note, What Can You Take Away From This?

Question 8 above highlights a pretty good point to remember in your interviews…

There are a lot of questions in an interview where the hiring manager values your thought process… sometimes even more than a correct answer. So if you’re stumped, talk out loud a bit and explain what you’re thinking. Ask a question if you need to. Try to break it down into smaller pieces. Specific knowledge can be taught but they can’t teach you problem-solving. That’s why they ask logical questions in a job interview, and why they ask questions where they  expect you to struggle or be unsure.

If you hear questions like this, it doesn’t mean you’re doing badly. Just stay calm, walk them through your thought process, show you take a logical approach, and you’ll have a great shot at getting hired (even if you don’t come up with the perfect answer in the end!)

You Can Get Hired Even if You Give “Wrong” Answers to These Questions

Here’s a quick story: My degree is in Finance, which means I took a good amount of Accounting classes too. Early in my career, I had a phone interview for an Accounting position. To make the story short, I could not answer even the most basic accounting questions. Really simple stuff that you learn your first year in college.

It had just been too long since college and I had forgotten even the basics. And I didn’t prepare well for the interview obviously! But I tried to stumble through it and remember what I could, talking about what I was thinking. Saying things like, “well, this can’t be right because ___. So it must be related to ___.” I made some progress. But I definitely didn’t arrive at the right answer, even after three minutes of walking myself and the interviewer through it out loud.

But I still got invited to the next round in the interview process (a full day, on-site interview).

Why? Because the hiring manager liked my approach to breaking down a problem that I didn’t immediately know how to solve. That’s why being transparent and showing your thought process is one of the tips for interviews that you’ll see me say over and over. And that’s the biggest takeaway that I hope you gain from reading these brain teaser questions above (along with entertainment). You can do the same thing I did and get more job offers… even if you give a few wrong answers to difficult questions like these!

The bottom line is: Don’t panic when you get a question you don’t know; use it as an opportunity to show exactly how you work through things. Be confident with it, relax, and smile. Remember… you’re giving the hiring manager what they want! If you have interviews coming up and want to prepare further, read the top 20 interview questions here.

I believe #1 is incorrect. I think it’s 1/5… am I missing something???

Question 3 can be done much more efficiently. All you have to do is to fill both jugs halfway. 3/2=1.5, 5/2=2.5, 1.5+2.5=4. It’s easier to estimate a half filled jug than filling a 3 gallon jug by one third. The only downside to this solution is that uncertainty is higher.

This is old: the research found brain teaser questions don’t do anything to evaluate job candidates other than stressing out the interviewee. Google has stopped using brain teasers.

Really interesting and good questions

Apologies if this has already been mentioned, but your answer to Q2 is not correct. You should be trying to solve the conditional probability problem P(Rain | YYY), and NOT 1 – P(lie, lie, lie).

The tricky part here is that you are not given all of the information you need to apply Bayes rule and solve the problem. Specifically, you additionally need to have a prior estimate of P(Rain). The interviewer/question purposefully withholds this information to see if you are able to identify how the problem should be solved, and if you can ask the right clarifying questions.

The solution, using Bayes Rule, is;

P(Rain | YYY) = P(Rain) * P(YYY | Rain) / P(YYY)

P(Rain) must come from the interviewer P(YYY) = P(Rain) * P(YYY | Rain) + P(~Rain) * P(YYY | ~Rain) P(YYY | Rain) = (2/3)^3 # All 3 friends tell the truth when it rains P(YYY | ~Rain) = (1/3)^3 # All 3 friends lie when it’s not raining

I hope this helps. Check out the following link for an excellent explanation and some further discussion of Bayesian vs frequentist approaches:

#3 is a correct solution but more complex than it needs to be. These companies also look for efficiency and not doubling your efforts.

Your Solution: 1. Fill up 3gal Bucket > Dump into 5gal bucket 2. Fill up 3gal Bucket > Dump 2gal into the remaining 2gal of area within the 5gal bucket 3. Empty 5gal Bucket > Dump 1gal within the 3gal bucket into the empty 5gal bucket 4. Fill up 3gal Bucket > Dump 3gal bucket completely into 5gal bucket that currently has 1gal within it.

This solution requires you to empty a bucket down the drain 1 time, fill a bucket from the faucet 3 times, and pour a bucket into a bucket 4 times.

Efficient Answer

1. Fill up 5gal bucket completely > Pour 3gal from 5gal bucket into the 3gal bucket to fill it up completely 2. Empty full 3gal bucket > Pour remaining 2gal from the 5gal bucket into the empty 3gal bucket 3. Fill up the 5gal bucket completely > Pour 1gal from the full 5gal bucket into the remaining 1gal of volume within the 3gal bucket.

This solution requires you to empty a bucket down the drain 1 time, fill a bucket from the faucet 2 times, and pour a bucket into a bucket 3 times.

If they ask you to solve the same problem, but dumping as little as possible down the drain, solution 2 is still your best bet. (1=5gal dumped, 2=3gal dumped because the problem is solved at the precise time you would need to dump it again for another step)

The only way that solution 1 is more efficient is if they ask you to solve the same problem USING as little water as possible. (1=9gal, 2=10gal)

Interesting. Thanks for the detailed reply.

The solution to Question 2 is incorrect.

You argue that the probability that at least one friend tells the truth is one minus the probability that all three friends are lying. This is correct. But you then say that we only need one friend to tell the truth for it to actually be raining. This may be true, but it takes into account scenarios where one friend is lying and the the other two are telling the truth, and vice versa. However, this is ignoring a key element: we already know that this has not happened! If all three friends are claiming that it is raining, then it is impossible that one is lying and two are telling the truth (analogously, it is impossible that two are lying and one is telling the truth) because they all said the same thing (and they know whether or not it is raining!).

One of two situations is possible: either it is raining in Seattle, or it is not. If (and only if) it is raining, then they are all telling the truth. If (and only if) it is not, then they are all lying. The probability that they are all telling the truth is 8/27; the probability that they are all lying is 1/27. The probability that they are telling the truth given that they all said the same thing is (8/27)/(1/27 + 8/27) = 8/9.

You are right. I also came to the answer 8/9 and wanted to comment that the given solution is wrong. I came across your comment and decided to just reply here :)

You’re right that the solution is incorrect, and you’re on the right track, but there’s actually not enough information, as the answer is dependent on the prior probability of it raining. If you let this prior probability be p, and apply Bayes’ rule, you should get that the probability that it’s actually raining, given that all three friends said yes, is 8p/(7p+1). If (and only if) you let p=1/2, then you recover an answer of 8/9.

This blog was… how do I say it? Relevant!! Finally I have found something which helped me. Cheers!

Are they asking questions to everyone or just software developers?? It seems geared toward developers mostly

It’s everyone, although you’ll expert more of these if your position involves analytical thinking, logic, problem solving, etc. Many Product Managers will face these questions. Also corporate lawyers! And many others along with software developers.

3 Key Tips to Solve Puzzle Problems in Interviews

Yes, these puzzles are tricky. Following are 3 key tips that will ensure that you will not stumble during the interview:

1. Clarify Everything Before you Start

Don’t jump into the solution, and do not make any assumptions. If any information seems missing, ask and clarify.

2. Explain Your Process

While solving the puzzle, explain your thought process to the interviewer. It allows your interviewer to see how you plan, think, reason, and solve complex problems under pressure. Always remember — these puzzles are more about showcasing your analytical skills than finding the right solution.

3. Provide a Solution to the Puzzle — One or More!

Use your reasoning and logical skills to deduce a solution to the puzzle, even if it’s not the correct solution. You can also discuss alternate methods. It’s more about your reasoning and deducing the solution, than finding the right solution.

• Describe a time when you had to solve a problem without managerial input. How did you handle it, and what was the result?
• Give an example of a time when you identified and fixed a problem before it became urgent.
• Share a situation where you predicted a problem with a stakeholder. How did you prevent it from escalating?
• Describe a time when you faced challenges in doing your job efficiently. How did you overcome them?
• Recall a time when you successfully used crisis-management skills.
• How would you handle a new project with great revenue potential but potential legal implications for the company?
• How do you determine when to solve a problem on your own or ask for help?
• Describe a time when you faced a difficult situation at work that required critical thinking and decision-making under pressure.
• Have you ever used intuition or prior experience to anticipate and address a problem effectively? Provide an example.
• Share an example of a project or task that initially seemed overwhelming. How did you approach it, and what strategies did you use to ensure successful completion?

1. Describe a time when you had to solve a problem without managerial input. How did you handle it, and what was the result?

This question assesses candidates’ ability to take initiative and solve problems independently. Look for their problem-solving approach, the actions they took, and the outcome of their efforts.

Sample answer:

“In my previous role, we encountered a sudden technical issue that disrupted our operations. As the team lead, I gathered all available information, analyzed the root cause, and facilitated a brainstorming session with the team. We implemented a temporary workaround and collaborated with the IT department to resolve the issue. Our proactive approach ensured minimal disruption, and we were able to restore normal operations within 24 hours.”

2. Give an example of a time when you identified and fixed a problem before it became urgent.

This question evaluates candidates’ ability to anticipate and address problems proactively. Look for their ability to identify potential issues and take preventive measures.

“While working as a project manager, I noticed a potential bottleneck in our production process that could have led to delays if left unaddressed. I conducted a thorough analysis, identified the root cause, and proposed process improvements. By implementing these changes proactively, we eliminated the bottleneck and increased efficiency. As a result, we consistently met project deadlines, and our team’s productivity significantly improved.”

3. Share a situation where you predicted a problem with a stakeholder. How did you prevent it from escalating?

This question assesses candidates’ ability to identify and mitigate potential conflicts. Look for their communication and problem-solving skills in managing stakeholder relationships.

“While working on a cross-functional project, I anticipated a miscommunication issue that could arise with a key stakeholder due to conflicting expectations. I scheduled a meeting with the stakeholder, listened to their concerns, and facilitated a discussion among the team members. By proactively addressing the issue, we established clear communication channels, built trust, and ensured a smooth collaboration throughout the project.”

4. Describe a time when you faced challenges in doing your job efficiently. How did you overcome them?

This question evaluates candidates’ ability to handle challenges and find solutions to improve efficiency. Look for their problem-solving strategies and their adaptability to overcome obstacles.

“In a previous role, I faced a situation where the workload significantly increased due to unexpected circumstances. To maintain efficiency, I assessed the situation, identified tasks that could be delegated, and communicated with my colleagues to seek their support. By redistributing responsibilities and fostering a collaborative environment, we successfully managed the increased workload without compromising quality or missing deadlines.”

5. Recall a time when you successfully used crisis-management skills.

This question assesses candidates’ ability to remain calm and make effective decisions under pressure. Look for their problem-solving approach and their ability to handle high-stress situations.

“In a previous role as a customer service representative, we experienced a sudden surge in customer complaints due to a product quality issue. I quickly coordinated with relevant departments, identified the root cause, and developed an action plan. By prioritizing urgent cases, maintaining open communication with affected customers, and providing timely updates, we regained customer satisfaction and prevented further damage to our brand reputation.”

6. How would you handle a new project with great revenue potential but potential legal implications for the company?

This question assesses candidates’ ability to balance potential risks and rewards. Look for their ethical considerations, problem-solving approach, and willingness to seek guidance when faced with legal implications.

“If faced with a project that carries both revenue potential and potential legal implications, I would approach it with caution and thorough evaluation. I would research and seek legal guidance to fully understand the implications and compliance requirements. I would then collaborate with legal experts, cross-functional teams, and stakeholders to develop a comprehensive plan that minimizes legal risks while maximizing revenue potential.”

7. How do you determine when to solve a problem on your own or ask for help?

This question assesses candidates’ judgment and collaboration skills. Look for their ability to assess situations and make decisions about when to seek assistance.

“When faced with a problem, I first evaluate its complexity and impact on the project or task at hand. If it’s within my capabilities and doesn’t significantly hinder progress, I take the initiative to solve it on my own. However, if the problem is complex or could have a significant impact, I believe in seeking help from relevant team members or subject matter experts. Collaboration often leads to more comprehensive and effective solutions.”

8. Describe a time when you faced a difficult situation at work that required critical thinking and decision-making under pressure.

This question assesses candidates’ ability to think critically and make sound decisions in challenging situations. Look for their problem-solving approach, decision-making process, and the outcomes of their decisions.

“In a previous role, I faced a tight deadline for a project with limited resources. It required careful resource allocation and prioritization. I gathered all available data, analyzed the project requirements, and consulted with team members. Through strategic planning and effective delegation, we managed to complete the project successfully within the given timeframe, exceeding client expectations.”

9. Have you ever used intuition or prior experience to anticipate and address a problem effectively? Provide an example.

This question assesses candidates’ ability to leverage intuition and past experiences to navigate problem-solving situations. Look for their ability to reflect on past situations, apply lessons learned, and make informed decisions.

“In a previous role, I noticed a recurring issue in our supply chain that had caused delays in the past. Drawing upon my prior experience, I anticipated the problem and suggested process improvements to streamline the supply chain. By implementing these changes, we minimized delays and improved overall efficiency, resulting in cost savings for the company.”

10. Share an example of a project or task that initially seemed overwhelming. How did you approach it, and what strategies did you use to ensure successful completion?

This question assesses candidates’ ability to tackle complex projects and break them down into manageable tasks. Look for their problem-solving approach, organization skills, and ability to persevere in the face of challenges.

“I once undertook a project that involved a significant amount of data analysis and reporting within a tight deadline. Initially, it felt overwhelming, but I broke it down into smaller tasks and created a detailed timeline. I prioritized the most critical aspects and sought assistance from colleagues with specialized skills. Through effective time management, collaboration, and diligent effort, we successfully completed the project on time and delivered high-quality results.”

Why you should ask candidates problem-solving interview questions

Employees will face challenges in their job. Before you decide on your next hire, use your interview process to evaluate how candidates approach difficult situations.

Problem-solving interview questions show how candidates:

• Approach complex issues
• Analyze data to understand the root of the problem
• Perform under stressful and unexpected situations
• React when their beliefs are challenged

Identify candidates who are results-oriented with interview questions that assess problem-solving skills. Look for analytical and spherical thinkers with the potential for technical problem solving.

Potential hires who recognize a problem, or predict one could potentially occur, will stand out. Candidates should also demonstrate how they would fix the issue, and prevent it from occurring again.

These sample problem-solving interview questions apply to all positions, regardless of industry or seniority level. You can use the following questions to gauge your candidates’ way of thinking in difficult situations:

Tips to assess problem-solving skills in interviews

• During your interviews, use hypothetical scenarios that are likely to occur on the job. It’s best to avoid unrealistic problems that aren’t relevant to your company.
• Examine how candidates approach a problem step-by-step: from identifying and analyzing the issue to comparing alternatives and choosing the most effective solution.
• Pay attention to candidates who provide innovative solutions. Creative minds can contribute fresh perspectives that add value to your company.
• When problems arise, employees should show commitment and a can-do attitude. Test candidates’ problem-solving skills in past situations. If they were determined to find the best solution as soon as possible, they will be great hires.
• Most complex situations require a team effort. Candidates’ previous experiences will show you how they collaborated with their colleagues to reach decisions and how comfortable they felt asking for help.
• If you’re hiring for a technical role, ask questions relevant to the work your future hires will do. Technical problem-solving interview questions, like “How would you troubleshoot this X bug?” will reveal your candidates’ hard skills and their ability to effectively address problems on the job.
• No answer. If a candidate can’t recall an example of a problem they faced in a previous position, that’s a sign they may avoid dealing with difficult situations. Canned answers. A generic answer like “Once, I had to deal with a customer who complained about the pricing. I managed to calm them down and closed the deal,” doesn’t offer much insight about the candidate’s thought process. Ask follow-up questions to get more details.
• Focus on the problem, not the solution. Identifying the problem is one thing, but finding the solution is more important. Candidates who focus too much on the problem may be too negative for the position.
• Feeling stressed/uncomfortable. It’s normal to feel slightly uncomfortable when put on the spot. But, if candidates are so stressed they can’t answer the question, that’s an indicator they don’t handle stressful situations well.
• Superficial answers. Candidates who choose the easy way out of a problem usually don’t consider all aspects and limitations of the situation. Opt for candidates who analyze the data you’ve given them and ask for more information to better dig into the problem.
• Cover up the problem or minimize its significance. Unaddressed problems could quickly escalate into bigger issues. Employees who leave things for later mightn’t be result-oriented or engaged in their jobs.

In conclusion, problem-solving interview questions provide valuable insights into candidates’ abilities to approach challenges, think critically, and provide effective solutions. By asking these questions and considering the tips provided, you can assess candidates’ problem-solving skills and make informed hiring decisions that align with your organization’s needs.

15 Common Problem-Solving Interview Questions

In an interview for a big tech company, I was asked if I’d ever resolved a fight — and the exact way I went about handling it. I felt blindsided, and I stammered my way through an excuse of an answer.

It’s a familiar scenario to fellow technical job seekers — and one that risks leaving a sour taste in our mouths. As candidate experience becomes an increasingly critical component of the hiring process, recruiters need to ensure the problem-solving interview questions they prepare don’t dissuade talent in the first place. 

Interview questions designed to gauge a candidate’s problem-solving skills are more often than not challenging and vague. Assessing a multifaceted skill like problem solving is tricky — a good problem solver owns the full solution and result, researches well, solves creatively and takes action proactively. 

It’s hard to establish an effective way to measure such a skill. But it’s not impossible.

We recommend taking an informed and prepared approach to testing candidates’ problem-solving skills . With that in mind, here’s a list of a few common problem-solving interview questions, the science behind them — and how you can go about administering your own problem-solving questions with the unique challenges of your organization in mind.

Key Takeaways for Effective Problem-Solving Interview Questions

• Problem solving lies at the heart of programming. 
• Testing a candidate’s problem-solving skills goes beyond the IDE. Problem-solving interview questions should test both technical skills and soft skills.
• STAR, SOAR and PREP are methods a candidate can use to answer some non-technical problem-solving interview questions.
• Generic problem-solving interview questions go a long way in gauging a candidate’s fit. But you can go one step further by customizing them according to your company’s service, product, vision, and culture. 

Technical Problem-Solving Interview Question Examples

Evaluating a candidates’ problem-solving skills while using coding challenges might seem intimidating. The secret is that coding challenges test many things at the same time — like the candidate’s knowledge of data structures and algorithms, clean code practices, and proficiency in specific programming languages, to name a few examples.

Problem solving itself might at first seem like it’s taking a back seat. But technical problem solving lies at the heart of programming, and most coding questions are designed to test a candidate’s problem-solving abilities.

Here are a few examples of technical problem-solving questions:

1. Mini-Max Sum  

This well-known challenge, which asks the interviewee to find the maximum and minimum sum among an array of given numbers, is based on a basic but important programming concept called sorting, as well as integer overflow. It tests the candidate’s observational skills, and the answer should elicit a logical, ad-hoc solution.

2. Organizing Containers of Balls  

This problem tests the candidate’s knowledge of a variety of programming concepts, like 2D arrays, sorting and iteration. Organizing colored balls in containers based on various conditions is a common question asked in competitive examinations and job interviews, because it’s an effective way to test multiple facets of a candidate’s problem-solving skills.

3. Build a Palindrome

This is a tough problem to crack, and the candidate’s knowledge of concepts like strings and dynamic programming plays a significant role in solving this challenge. This problem-solving example tests the candidate’s ability to think on their feet as well as their ability to write clean, optimized code.

4. Subarray Division

Based on a technique used for searching pairs in a sorted array ( called the “two pointers” technique ), this problem can be solved in just a few lines and judges the candidate’s ability to optimize (as well as basic mathematical skills).

5. The Grid Search 

This is a problem of moderate difficulty and tests the candidate’s knowledge of strings and searching algorithms, the latter of which is regularly tested in developer interviews across all levels.

Common Non-Technical Problem-Solving Interview Questions 

Testing a candidate’s problem-solving skills goes beyond the IDE . Everyday situations can help illustrate competency, so here are a few questions that focus on past experiences and hypothetical situations to help interviewers gauge problem-solving skills.

1. Given the problem of selecting a new tool to invest in, where and how would you begin this task? 

Key Insight : This question offers insight into the candidate’s research skills. Ideally, they would begin by identifying the problem, interviewing stakeholders, gathering insights from the team, and researching what tools exist to best solve for the team’s challenges and goals. 

2. Have you ever recognized a potential problem and addressed it before it occurred? 

Key Insight: Prevention is often better than cure. The ability to recognize a problem before it occurs takes intuition and an understanding of business needs. 

3. A teammate on a time-sensitive project confesses that he’s made a mistake, and it’s putting your team at risk of missing key deadlines. How would you respond?

Key Insight: Sometimes, all the preparation in the world still won’t stop a mishap. Thinking on your feet and managing stress are skills that this question attempts to unearth. Like any other skill, they can be cultivated through practice.

4. Tell me about a time you used a unique problem-solving approach. 

Key Insight: Creativity can manifest in many ways, including original or novel ways to tackle a problem. Methods like the 10X approach and reverse brainstorming are a couple of unique approaches to problem solving. 

5. Have you ever broken rules for the “greater good?” If yes, can you walk me through the situation?

Key Insight: “Ask for forgiveness, not for permission.” It’s unconventional, but in some situations, it may be the mindset needed to drive a solution to a problem.

6. Tell me about a weakness you overcame at work, and the approach you took. 

Key Insight: According to Compass Partnership , “self-awareness allows us to understand how and why we respond in certain situations, giving us the opportunity to take charge of these responses.” It’s easy to get overwhelmed when faced with a problem. Candidates showing high levels of self-awareness are positioned to handle it well.

7. Have you ever owned up to a mistake at work? Can you tell me about it?

Key Insight: Everybody makes mistakes. But owning up to them can be tough, especially at a workplace. Not only does it take courage, but it also requires honesty and a willingness to improve, all signs of 1) a reliable employee and 2) an effective problem solver.

8. How would you approach working with an upset customer?

Key Insight: With the rise of empathy-driven development and more companies choosing to bridge the gap between users and engineers, today’s tech teams speak directly with customers more frequently than ever before. This question brings to light the candidate’s interpersonal skills in a client-facing environment.

9. Have you ever had to solve a problem on your own, but needed to ask for additional help? How did you go about it? 

Key Insight: Knowing when you need assistance to complete a task or address a situation is an important quality to have while problem solving. This questions helps the interviewer get a sense of the candidate’s ability to navigate those waters. 

10. Let’s say you disagree with your colleague on how to move forward with a project. How would you go about resolving the disagreement?

Key Insight: Conflict resolution is an extremely handy skill for any employee to have; an ideal answer to this question might contain a brief explanation of the conflict or situation, the role played by the candidate and the steps taken by them to arrive at a positive resolution or outcome. 

Strategies for Answering Problem-Solving Questions

If you’re a job seeker, chances are you’ll encounter this style of question in your various interview experiences. While problem-solving interview questions may appear simple, they can be easy to fumble — leaving the interviewer without a clear solution or outcome. 

It’s important to approach such questions in a structured manner. Here are a few tried-and-true methods to employ in your next problem-solving interview.

1. Shine in Interviews With the STAR Method

S ituation, T ask, A ction, and R esult is a great method that can be employed to answer a problem-solving or behavioral interview question. Here’s a breakdown of these steps:

• Situation : A good way to address almost any interview question is to lay out and define the situation and circumstances. 
• Task : Define the problem or goal that needs to be addressed. Coding questions are often multifaceted, so this step is particularly important when answering technical problem-solving questions.
• Action : How did you go about solving the problem? Try to be as specific as possible, and state your plan in steps if you can.
• Result : Wrap it up by stating the outcome achieved. 

2. Rise above difficult questions using the SOAR method

A very similar approach to the STAR method, SOAR stands for S ituation, O bstacle, A ction, and R esults .

• Situation: Explain the state of affairs. It’s important to steer clear of stating any personal opinions in this step; focus on the facts.
• Obstacle: State the challenge or problem you faced.
• Action: Detail carefully how you went about overcoming this obstacle.
• Result: What was the end result? Apart from overcoming the obstacle, did you achieve anything else? What did you learn in the process? 

3. Do It the PREP Way

Traditionally used as a method to make effective presentations, the P oint, R eason, E xample, P oint method can also be used to answer problem-solving interview questions.  

• Point : State the solution in plain terms. 
• Reasons: Follow up the solution by detailing your case — and include any data or insights that support your solution. 
• Example: In addition to objective data and insights, drive your answer home by contextualizing the solution in a real-world example.
• Point : Reiterate the solution to make it come full circle.

How to Customize Problem-Solving Interview Questions 

Generic problem-solving interview questions go a long way in gauging a candidate’s skill level, but recruiters can go one step further by customizing these problem-solving questions according to their company’s service, product, vision, or culture. 

Here are some tips to do so:

• Break down the job’s responsibilities into smaller tasks. Job descriptions may contain ambiguous responsibilities like “manage team projects effectively.” To formulate an effective problem-solving question, envision what this task might look like in a real-world context and develop a question around it.  
• Tailor questions to the role at hand. Apart from making for an effective problem-solving question, it gives the candidate the impression you’re an informed technical recruiter. For example, an engineer will likely have attended many scrums. So, a good question to ask is: “Suppose you notice your scrums are turning unproductive. How would you go about addressing this?” 
• Consider the tools and technologies the candidate will use on the job. For example, if Jira is the primary project management tool, a good problem-solving interview question might be: “Can you tell me about a time you simplified a complex workflow — and the tools you used to do so?”
• If you don’t know where to start, your company’s core values can often provide direction. If one of the core values is “ownership,” for example, consider asking a question like: “Can you walk us through a project you owned from start to finish?” 
• Sometimes, developing custom content can be difficult even with all these tips considered. Our platform has a vast selection of problem-solving examples that are designed to help recruiters ask the right questions to help nail their next technical interview.

To ensure the effectiveness of the solution, I implemented a monitoring system that provided real-time feedback and allowed for proactive adjustments, thus demonstrating a commitment to continuous improvement and long-term resilience.”

15. How has your problem-solving technique evolved over the course of your career?

With experience, exposure to various challenges, and the acquisition of knowledge, problem-solving skills mature. Your adaptability and growth in your approach to tackling issues reveal how you learn from past experiences and refine your methods.

When responding, it’s important to give concrete examples that illustrate a progression in your problem-solving abilities. Start with an early career challenge, describe the approach taken then, and contrast it with a more recent problem and the evolved techniques used to solve it. Highlight any specific lessons learned, mentors who influenced your methods, or training that contributed to your development. This not only shows your problem-solving growth but also demonstrates self-reflection and a commitment to professional development.

Example: “ Early in my career, my problem-solving approach was primarily reactive and often relied on conventional wisdom. For instance, when faced with a challenging project, I would tackle issues as they arose, using established methods without much anticipation of potential complications. This sometimes led to inefficiencies and a piecemeal resolution of problems.

As I gained experience, I began to adopt a more proactive and systematic approach. I learned the importance of defining the problem accurately, gathering data, and analyzing it before jumping to solutions. For example, when a complex issue presented itself recently, I utilized root cause analysis to identify the underlying factors contributing to the problem. This allowed me to develop a comprehensive strategy that addressed the core of the issue rather than just its symptoms. I also started incorporating cross-disciplinary techniques, such as design thinking and agile methodologies, to foster creative solutions and adapt quickly to changing circumstances. This evolution in my problem-solving technique has resulted in more innovative and sustainable outcomes, as well as a significant reduction in the time and resources required to resolve issues.”

16. Describe an occasion where you identified a potential problem before it occurred and preemptively addressed it.

Strategic thinking and foresight are hallmarks of recognizing and mitigating potential problems before they manifest. Your ability to analyze situations, anticipate challenges, and take proactive measures is what this question aims to uncover.

When responding, outline a specific situation where you noticed warning signs or patterns that suggested a future issue. Detail the steps you took to evaluate the risk and the actions you implemented to prevent the problem. Be sure to highlight your thought process, the resources you utilized, and the outcome of your intervention. This will demonstrate not only your problem-solving skills but also your ability to act decisively and effectively under potential pressure.

Example: “ On one occasion, I recognized that a critical project was at risk due to potential supply chain disruptions. By analyzing vendor delivery patterns and global market trends, I identified a pattern of delays that could severely impact our timeline. To mitigate this risk, I proactively engaged with alternative suppliers and renegotiated terms with existing vendors to ensure priority delivery. Additionally, I implemented a real-time tracking system for supply chain management, allowing for immediate response to any logistical hiccups.

This preemptive strategy not only averted a bottleneck in our project but also strengthened our vendor relationships and improved our overall supply chain resilience. The project was completed ahead of schedule with cost savings from the more competitive supplier terms. This experience underscored the importance of vigilance and adaptability in preemptive problem-solving.”

17. When dealing with unknown variables, how do you proceed in formulating a solution?

Across all industries, problem-solving skills demonstrate an individual’s ability to adapt and find solutions in uncertain situations. Your critical thinking and analytical abilities, initiative, resourcefulness, and creativity are all assessed through this question.

When responding to this question, outline a structured approach that begins with identifying what is known and what is not. Discuss how you gather additional information, break down the problem into manageable parts, and prioritize the variables that will have the most significant impact on the solution. Mention any tools or techniques you use, such as root cause analysis or brainstorming sessions, and how you weigh potential outcomes to make informed decisions. It’s also beneficial to provide a specific example of a past situation where you successfully navigated through unknowns to resolve a problem.

Example: “ When confronted with unknown variables, my approach is to first delineate the boundaries of what is known and leverage that as a foundation. I systematically categorize the unknowns based on their potential impact and relevance to the problem at hand, prioritizing them to efficiently direct my research and analysis efforts. I employ tools such as root cause analysis to drill down into the underlying issues and utilize brainstorming sessions with stakeholders to explore diverse perspectives and solutions.

In a past situation, I was faced with a complex problem where the cause was obscured by several interacting unknown variables. By applying a combination of Pareto analysis and iterative hypothesis testing, I was able to isolate the most significant factors. This methodical approach allowed me to not only identify the root cause but also to develop a targeted solution that addressed the core of the problem rather than just its symptoms. The result was a sustainable resolution that prevented recurrence and optimized system performance.”

18. Can you recount a project where iterative problem-solving was crucial to success?

Recognizing when a problem is complex enough to require iterative techniques is a sign of effective problem-solving. This question delves into your endurance, adaptability, and analytical skills, as well as your willingness to engage in continuous improvement.

When responding, candidates should select a project that had multiple layers of complexity, requiring them to apply an iterative approach. It’s important to describe the initial problem, the steps taken to address it, and how feedback or results from each phase guided subsequent actions. Highlighting collaboration with team members and how their input shaped the evolving solution can demonstrate both teamwork and leadership skills. Remember to articulate the lessons learned and how the experience has honed your problem-solving abilities for future challenges.

Example: “ In a project aimed at optimizing a complex supply chain network, iterative problem-solving was essential due to the dynamic nature of logistics and varying market demands. The initial problem was a bottleneck in the distribution process, which led to delays and increased costs. The initial strategy involved analyzing the existing workflow and identifying key areas where efficiency could be improved. However, it quickly became apparent that the solution required a deeper, multi-stage approach.

The first iteration of the solution involved implementing a new inventory tracking system to provide real-time data on stock levels. While this improved visibility, it didn’t fully resolve the bottleneck. Feedback from this phase indicated that transportation scheduling was also a contributing factor. The second iteration focused on developing a more flexible scheduling system that could adapt to changing demands. This significantly reduced the delays, but there was still room for improvement. Further iterations involved cross-functional collaboration to refine the process, incorporating insights from the sales, procurement, and warehouse teams to align all aspects of the supply chain.

Each phase of the solution was informed by the results and feedback of the previous one, leading to a comprehensive and adaptive system that significantly improved overall efficiency. This iterative approach not only resolved the immediate issue but also provided a framework for continuous improvement in the supply chain. The experience underscored the importance of flexibility, cross-functional collaboration, and the willingness to adapt solutions based on iterative feedback, all of which have become integral to my problem-solving toolkit.”

19. What role does customer feedback play in your problem-solving strategy?

Customer feedback is critical in understanding what is working well and what needs improvement from the user’s perspective. How you value direct input from users and integrate that information into a responsive and adaptive problem-solving process is what organizations look for.

To respond effectively, candidates should articulate a structured approach that showcases active listening, critical analysis of feedback, and integration of actionable insights into problem-solving efforts. They should give examples of how they have used customer feedback to identify the root cause of a problem, generate solutions, and measure the effectiveness of those solutions post-implementation. Additionally, candidates can discuss how they maintain a feedback loop with customers to ensure continuous improvement and customer satisfaction.

Example: “ Customer feedback is integral to my problem-solving strategy as it provides direct insight into the user experience and highlights areas that may not align with our intended outcomes. By actively listening to feedback, I can identify patterns and specific pain points that customers face. This information is critical for root cause analysis, allowing me to pinpoint the underlying issues rather than just addressing surface-level symptoms.

Incorporating customer feedback, I prioritize issues based on their impact and frequency, developing solutions that are both effective and efficient. Post-implementation, I leverage feedback to assess the success of the solution, ensuring it meets customer expectations and resolves the identified problems. This creates a feedback loop that fosters continuous improvement and demonstrates to customers that their input is valued and drives change, ultimately enhancing customer satisfaction and loyalty.”

20. How do you distinguish between symptoms and underlying causes when analyzing a problem?

Differentiating between what is immediately observable and the root issues that trigger these manifestations denotes a person’s analytical prowess and capacity for critical thinking. Your methodology in dissecting issues is tested, ensuring long-term solutions rather than temporary fixes.

When responding, it’s essential to articulate a structured approach: start by describing how you gather and analyze information to identify patterns or commonalities that may point to underlying causes. Provide examples from past experiences where you successfully identified the root of a problem, perhaps by using specific tools or frameworks like the “5 Whys” method. Emphasize your attention to detail and your persistence in exploring beyond the obvious, highlighting how your approach led to effective and sustainable solutions.

Sample Logic Puzzles Given at Job Interviews

Companies today are doing whatever they can to try to hire only the best and the brightest. To accomplish this, some companies – Most notably, Microsoft and other IT companies – have added logic puzzles to their standard interview questions. Logic puzzles are designed to provide the company with insight into how well the applicant can solve problems and think outside the box for solutions. They are a great on-the-spot test of intelligence and provide almost as much information as an applicant’s work history. Below are some of the logic puzzles given at job interviews and their answers.

Sample Job Interview Logic Puzzles

Question: You have 8 jars of the same size and shape. Seven of the jars weigh 5 ounces while the eighth jar weights 6. You have a scale you can use to measure the jars but you can only measure twice. How do you find out which is the heavier jar?

Answer: You take two jars away. Put 3 jars on one side of the scale and 3 jars on the other side. Measure. If neither of them are heavier, the jar must have been in one of the two you took away. Measure and you will find the jar. If one of the scales did tilt, take 1 jar away of the remaining 3 and measure the two remaining jars on each side of the scale. If one tilts, that is the heavier jar. If neither tilts, the one remaining jar must be the heavy one.

Question: A snail is at the bottom of a 30 foot well. Every hour the snail is able to climb up 3 feet, then immediately slide back down 2 feet. How many hours does it take for the snail to get out of the well?

Answer: 28 hours. The snail is travelling at one foot per hour, except on the 28 th hour the snail has already reached the top of the well, so it will not slide down the 2 feet.

Question: There are 3 light bulbs in a hidden room and 3 switches outside the room that correspond to those light bulbs. You do not know which switch affects which bulb and you cannot see inside of the room. You are allowed to go inside of the room only one time. How do you find out which switch corresponds to which bulb?

Answer: Turn on two switches and wait for a while. Then turn off one switch and go inside the room. The bulb that is still on corresponds to the switch that is still on. Touch the remaining bulbs. The hotter bulb is the switch that you turned off, and the remaining bulb is the switch that you never turned on.

Answering Logic Puzzles

Logic puzzles can be difficult. The key to answering logic puzzle interview questions is not just in solving the problem, but in using sound reasoning. If you don’t know an answer, try your best to explain your thought process. Even if you are wrong, you should be able to impress the interviewer at most job interviews.

What is the Water Jug Problem in AI?   

The Water Jug Problem in AI is a classic puzzle often used to illustrate problem-solving and search algorithms. It involves two jugs with known capacities and an unlimited water supply. The challenge is to measure a specific amount of water using these jugs. For example, given a 3-litre and a 5-litre jug, the goal might be to measure exactly 4 litres .   

The problem requires figuring out a sequence of actions (filling, emptying, and transferring water between jugs) to achieve the desired measurement. It's a practical example of how AI systems can be designed to explore possible states and actions to reach a solution, demonstrating concepts like state space, goal state, and operators. This problem helps understand the importance of planning and decision-making in AI.  

Solving the Water Jug Problem  

After understanding the basics of the Water Jug Problem in AI, it's time to explore the methods used to solve it. These methods include various search algorithms and optimisation techniques, each offering unique approaches to finding the solution.  

1) Breadth-First Search (BFS)  

Breadth-First Search (BFS) is a fundamental algorithm in computer science, particularly useful in solving the Water Jug Problem . BFS explores all possible moves level by level, starting from the initial state. In the context of the Water Jug Problem , this means systematically filling, emptying, and transferring water between jugs, considering every possible state that can be reached from the current state.  

To implement BFS, you use a queue to keep track of the current state and all potential subsequent states. The algorithm begins by enqueueing the initial state, then iteratively dequeues states to explore their neighbouring states. For example, if you have a 3-litre jug and a 5-litre jug, BFS would first consider the states where each jug is either filled to its capacity or emptied. It then explores transferring water between the jugs in various configurations.  

The main advantage of BFS is its ability to find the shortest path to the goal state, ensuring the minimum number of moves. However, BFS can be memory-intensive, as it needs to store all possible states . Despite this, BFS is particularly effective when the solution requires exploring all possibilities or when the search space is relatively small , making it a good fit for problems like the Water Jug Problem .

2) Depth-First Search (DFS)  

Depth-First Search (DFS) takes a different approach by exploring one potential path to its end before backtracking and trying alternative paths. In the Water Jug Problem , DFS starts from the initial state and continues to explore the deepest level of the state space before moving back to explore other branches. This is implemented using a stack, which helps in maintaining the sequence of states being explored.  

DFS is often more memory-efficient than BFS, as it only needs to store the current path and backtrack when necessary. However, one downside is that DFS does not guarantee finding the shortest path to the solution. In some cases, it may even explore paths that are far longer than necessary, particularly if the solution lies closer to the root of the search tree.  

In the water jug problem, DFS might fill one jug completely and then attempt to pour water into the other jug until it is full or empty before moving to another operation. This method can be advantageous when you need to explore deep solutions or when the search space is large, and the solution lies deep within it. However, care must be taken to avoid infinite loops or repeatedly visiting the same states, which can be mitigated by keeping track of visited states.  

3) Pruning  

Pruning is a technique used in search algorithms to eliminate paths that are unlikely to lead to a solution, thereby improving efficiency. In the context of the Water Jug Problem , pruning can significantly reduce the number of states that need to be explored, speeding up the search process.  

One common pruning method involves keeping track of visited states to prevent re-exploration. For instance, if you have already explored the state where the 3-litre jug is full, and the 5-litre jug is empty, there is no need to revisit this state. This prevents redundant calculations and helps the algorithm focus on new, unexplored paths.  

Another pruning strategy involves identifying and ignoring moves that do not contribute to reaching the goal. For example, if the goal is to measure 4 litres and you find yourself repeatedly filling and emptying the same jug without making progress, these actions can be pruned from consideration. Pruning is particularly useful in the water jug problem when combined with BFS or DFS, as it helps manage the search space more effectively. It can also be combined with heuristics to further refine the search process, making it faster and more efficient. By reducing the number of unnecessary or unproductive states, pruning helps in achieving the solution more quickly and with less computational effort.
